From p. 29: " … j'eus la pensée de faire arracher des racines sur les vignes déjà atteintes pour les examiner attentivement … En promenant ma loupe sur l'épiderme de ces racines de vigne, je découvris ainsi quelques petits points jaunes que je montrai immédiatement à M. Planchon … " ( … I had the thought of pulling out the roots of the vines that were already affected in order to examine them attentively … By scanning the epidermis of the vine's roots with my lens, I thus discovered some little yellow points that I showed immediately to Mr. Planchon … ).

"C'est pour cela que, dès le début de l'invasion du Phylloxera, j'ai émis l'opinion que cet insecte, si éminemment parasite, ne pouvait être la cause première de la mort des vignes, mais seulement la conséquence de leur état maladif." (It is for that [reason] that, from the start of the Phylloxera invasion, I have expressed the opinion that this insect, so eminently parasitic, could not be the first cause of the death of the vines, but only the consequence of their sickly condition.)
